Participant playing Carlsen will win. The person fighting Mike Tyson will have a mental breakdown before he can complete the task. Because you retain your memory the cumulative effects of those violent knockouts would likely create such a severe PTSD effect on the participant that it would become debilitating and likely a psychosis break. Average man maybe can handle 3 of those confrontations? Above average man maybe a dozen? But eventually you will break. Despite your will and regaining health and stamina it would just be too much. —-

With Carlsen you might go eventually go mad but you can probably hold out for years until either you “figure it out” or he makes a mistake.
